CARBONATOR.

SPECIFICATION forming-part of Letters Patent No. 724,727, dated A 'ri17,1903-. Application filed September 25, 1902:. Serial No. l Q4,854=. (No model.)

To (ZZZ whom it may concern:

Be it known that I, EDWARD E. MURPHY, of Chelsea, county of Suffolk, and State of Massachusetts, have invented an Improvement in Carbonators, of which the following description, in connection with the accompanying drawings, is a specification, like letters On the drawings representing like parts.

The present invention relates to a carbon- Io ator and is embodied in certain novel features of construction and arrangement whereby the gas and water are more thoroughly intermin gled, the water purified, and the supply of Water automatically controlled to the best ad- I 5 vantage.

The invention is herein shown as embodied in a carbonator having a receiver which may be of the usual construction adapted to receive water and gas, the former being pumped into the receiver while the latter is admitted from any suitable source, such as one of the gas-tubes now in commercial use. In the construction shown the water is arranged co-be supplied from an ordinary pipe system, such 2 5 as a city supply, a portion of the water being utilized to operate a pump, which in turn acts upon the water supplied thereto through a branch pipe to force the water into the receiver against the pressure of the gas, this being a common expedient and chosen merely as an illustration, since it forms no part of the invention. The water which is supplied to the receiver by the pump is purified by means of a filter comprising inner and outer chambers, one of which constitutes the inletand the other the outlet, the inner chamber having openings in the walls thereof and a corrugated outer surface to afiord channels whereby the water can reach the said open- 0 ings, the said'surface being covered with a foraminous metal covering, which in turn is covered with porous material, such as felt. The water, therefore, in passing through the filter must permeate the felt, which retains all 4 5 the impurities, it being practicable to remove the felt or whatever material is used from time to time when fouled. The gas is supplied to the receiver through an inlet near the bottom thereof, the said inlet terminating in 0 a chamber having a series of outlets each of which is formed of some porous material which divides u p the inflowing cu rrent of gas, so that it dissolves more readily in the water which is in the receptacle. chamber may be screw-threaded, so as to re-' ceive pieces of ratan which may be externally threaded and screwed into the said outlets, the fiber of ratan being such that each piece has a number of small longitudinal passages extending through it, thus constituting a suitable outlet for the purpose. further in the rapid and intimate mixture of the gas and water, the receiver is provided with'a water-inlet of novel construction and arrangement which constitutes not only a spraying-inlet for the water, but also an inspirator, so that a certain amount of gas is entrained by the water, which, therefore, when it enters the receiver is very finely divided or fogged, thus mixing intimately with the gas and becoming thoroughly carbonated as it collects inthe receiver. To control the supply of water, the inlet-passage which leads from the pump to the receiver is provided with a valve of novel construction and arrangement, which valve is controlled by a ball within the receiver, the said ball being solid and of nearly the same specific gravity as that of the Water, so that it must be almost entirely submerged in order to be supported. The said ball when not so supported acts upon the valve to open the same, there being an operating member interposed between the ball and the valve-stem, which passes through a stuffing-box, so that the valve can be removed for cleaning or repairs without opening the receiver or reducing the gas-pressure therein, the Water-inlet pipe being provided also with a check-valve, which prevents the escape of gas when the controlling-valve is removed.

Figure 1 is a vertical section of a carbonator embodying the invention; Fig. 2, an enlarged sectional detail showing the water-inlet; Fig. 3, a detail showing the means for spraying the water; Fig. 4, a horizontal section on the line-0c of Fig. 1, showing the gasinlet; and Fig. 5, a vertical section showing a portion of the gas-inlet.

The receiver A, which maybe of the usual shape and dimensions, is adapted to be sup- The outlets from the To aid iOO plied with gas through an inlet-pipe B, leading from any suitable source, and with water through an inlet-pipe 0, leading from a pump D, which may be of any suitable or usual type, being herein shown as a motor-pump adapted to be driven by Water entering through a pipe E, having a pressure-regulator or reducing-valve E the water to be carbonated being supplied to the pump proper through a branch pipe F from the same source. To purify the water which is to be carbonated, the supply-pipe F is shown as provided with a filter, which comprises a chamber f, into which the water passes from the pipe F,

and another chamber f provided with an outlet f from which the water passes to the pump D. The chamber f is closed except for the outletf and one or more openings f in the wall thereof, the said openings f being herein shown as narrow slits, while the outer wall of the chamber f is corrugated, as indicated atfithe corrugations forming channels along which the water can flow toward theopeningsf. Surroundingthecorrugated outer wall of the chamberf is a foraminous metallic coveringf, over which is a further coveringf", of porous material, preferably a fabric such as felt, the said covering f being preferably in the form of a sleeve, which is drawn tightly over the outer surface of the said metallic covering f. The wall of the outer chamberfis shown as a cylindrical shell adapted to be screwed onto a coupling-piece f so that it can be readily removed in order that the coveringf may be taken oil? and replaced as frequently as may be desirable. The filtered water is supplied by the pump D to the pipe 0, which is coupled to the top of the receiver as by a gland C the water from the pipe being subjected, before it enters the receiver, to the action of a spraying device of novel construction and arrangement. (See Fig. At the upper portion of said spraying device is a conical strainer c, the purpose of which is to intercept any foreign su bstauces which may come from the pump, the water passing through the said strainer into a chamber 0 which is shown as formed in a tubular member 0 having a shoulder 0 supported in the upper portion of a shell 0 which passes through an opening in the top of the receiver A and is clamped therein by means of a nut 0 The member 0 is so shaped as to alford an annular space 0 around the member 0 into which space the gas in the receiver A rises, so that the said member is always surrounded by gas under pressure.

Secured to the lower end of the member 0 is the spraying device proper, the said spraying device being shown as provided with two or more passages c to receive the Water from the chamber a, the said passages being provided with lateral inlets c communicating with the annular space 0 so that as the water passes through it will entrain with it a certain amount of gas. In the lower end of this member is secured a cap 0 having a small aperture 0 which constitutes the water-outlet, the said cap being shown as hemispherical in shape, with the outlet 0 at the middle. Interposed between the cap and the waterpassages 0 there is a wall or partition e having openings 0 for the water, the said opeuings, as indicated in Fig. 3, being formed diagonally through the wall, so that the water, with the entrained gas, in passing through is deflected against the walls of the shell 0 and given a rotating or whirling movement,which results in causing the water to be finely divided or sprayed as it issues from the opening 0. This spraying of the water, in conjunction With the admixture of gas entrained through the passages 0 causes the water to enter the receiver in the form of very finelydivided spray or mist, so that it mixes thoroughly with the gas before it collects at the bottom of the receiver. The gas which en ters the receiver A at the bottom from the pipe B is shown as led into the receiver through a. passage b in a coupling-piece b, the said passage b communicating with the pipe which leads to a chamber 1) inside-of the receiver. The said chamber is provided with one or more outlets, the said outlets being preferably radially arranged around the chamber b, which is cylindrical in shape, and each outlet-opening is provided with a filling of foraminous material for the purpose of finally dividing the gas as it flows through. As herein shown,the outlets are in the form of internally-threaded radial openings through the wall of the chamber b and each opening contains a short section of ratan b having a thread cut on its outer surface, so that it can be screwed into the opening, as shown in Figs. 4 and 5. While it'is not essential that ratan should be used for this purpose, this substance is especially available on account of its hardness, which ad mits of screw-threads being cut on the outer surface, and it is also straight-grained, there being a large'number of fine parallel openings extending longitudinally through the wood.

It will be seen that the carbonating is thoroughly and rapidly accomplished by the expedients above described, the water on entering the body of gas being finely divided, so that each particle is acted upon by the gas, while the gas entering the accumulated body of water is also finely divided, thus acting in the same way. 7

In order to control the supply of water in the receiver, the inlet-pipe O is provided with a valve 01, shown as cooperating with a valveseat (1 formed in a coupling-piece d", which contains inlet and outlet passages d and d secu red, respectively,- to sections of the main inlet-pipe C. The said coupling-piece d is arranged to be secured, as indicated, to a tubular member d secured in the wall of the receiver A, the said tubular member having pivotally supported therein a lever e, which is provided with a ball .9 inside of the receiver. The said lever e is so arrangedas to cooperate with a rod d which projects through a suitable stuffing-box in the coup ling cl and acts upon the end of the valve d, which is normally held toward its seat by means of a spring (1 The ball e is made solid and is nearly equal in weight to an equal bulk of water, so that it has to be almost submerged in order to be supported in the position shown in Fig. 1. As the level of the water becomes lowered, therefore, the ball will drop, and the lever e, acting through the rod d will unseat the valve 01, thus permitting the flow of water into the receiver A, the supply thus being automatic. In order to shut 01f the supply, if desired, and prevent the automatic operation, the valve d is also arranged to be operated upon by a manuallyoperating'device (1 shown as a rod screwthreaded in a supplemental coupling-piece al the said rod being arranged to act directly upon the valve 01 when screwed in, so as to hold the said valve seated. As indicated in Fig. 1, the said coupling-piece (1 may be removed to afford access to the valve 01, there being no passage for the escape of fluid from the receiver when said valve is removed, since the actuating-rod d is packed, as described. The pipe 0 is further provided with a check-. valve 0 which prevents the escape of gas when the valve is removed, so that these parts are readily accessible for cleaning or repairs.

. It is desirable also to provide the pipe 0 with an additional ,check-valve0 below the coupling d in order to prevent the escape of gas in case the valves above should leak.

The carbonated water is drawn from the carbonator through an outlet-pipe G, (see Fig. 4,) which is preferably secured in the coupling 19, the said coupling having the passage W", to which is secured a pipe 12 projecting into thereceptacle to receive the carbonated water.
